Specification of Letters Patent.

' PatentedNotn; r, 1916." 19,1914. Serial no. 819,637.

The invention is shown as applied to ,a

typewriting machineof the usual Underwood type, wherein a platen 1ismounted on r a shaftf2,vjournaled in: bearings on a platen; frame 3,which is moved along'the Punting 'POlIltbf the type 4,-'by a carriagefi,the. platen-frame being included in, or forming Part of, said. carriage.At the end ofeach- "line of writing, the c arriageY5 isreturned to f thestarting point by means of a lever4.6,- v mounted on the said carriage,which? level",

' is also adapted to rotate or 'line space the platen, by-driving backaplunger Or'slide. v *7, thereby operating a pawl S'carried hy-said- 9that is fast on the platenshaft 2. The paper or work-sheets 10 are supprted in a rearwardly-inclined vertical stack in r a magazine composed ofa rear-framewallf 11, side wings or walls12, and a base-13,] which base,while beingslightly uptil'ted in J its forward extension from rear wall11 to slide, to feed a ratchet or line-space wheel- 0."

frictional feed rolls .14, mounted 0113a shaft j 15. tliatfis journaledin bearings therefor the side wings 12, by means of an auxiliary rearframe 16, lying'between the Wall 11. p

and the rear surface of.said stack ofqsheets, said frame 16 havingupwardly-extending.

auxiliary frame 1 6, where they exert out-1.

sheets against the feed rolls 14: with the 7' The loose sheets of thestack contained the magazine aforesaid, are held fromfall ing forwardlyout of said magazine, :by

means of a vertical arm" -18 ;arranged at the back of frame 11, andhaving vertically slid will be in front of the upper margins of thesheets in the magazine, and said arm is retained or set in that adjustedposition by means of a wing-screw 11, threaded into" frame 11, through avertical slot 18 in said arm.

The sheets 10 are fed downwardly toward the platen by the rolls 14, ofwhich two are shown in the drawings, each being provided with frictionalsurfaces. Of course, the particular number of feed rolls is unimportant,excepting with regard to the uniformity of the frictional drag theyapply to the sheets, and for this purpose they may be employed insuitable number and location. To enhance their serviceability, the

rolls 14 are provided with a peripheral surfacing of frictionalmaterial, and in the example shown, I have indicated at 14 a number ofcorrugated bands as placed frictional contact-with the forward surfaceof the front sheet 10 in the magazine.

Under the frictional arrangement referred to the rotation of the rolls14, clockwise in Fig. 4, will cause the forward sheet 10 to be feddownwardly from the stack, passing, as shown in Fig. 4, between thedown-turned lip 13 of the base 13 and saidrolls, and being guided thenceto the platen and its feed rolls 28, by forwardly-depending guidefingers 19, which extend from a front bar 19*" connecting the wings 12,and by the usual paper shelf or table 20," upon which latter themagazine may be mounted. In the example shown, where the table 20 hasthe upper beaded or hooked edge 21, the lower rear edge of the frame 11may have hook-like lugs 11 to straddle said beaded edge and thus effecta locking engagement with said table.

The magazine is otherwise removably con- 'nected to thetypewritingmachine by .a

rod 22, passed through a support or lateral extension 12 of one of theside wings 12 of the magazine frame, said extension 12 being supportedin a lower plane than base 13 by a connecting web 12 Said rod 22 has ahook 22 at its lower end for engagement with a rod 23 or other member onthe platen frame. The rod 22, above extension 12 has a thread to receivea knurled nut 22", whereby it may be drawn tautly for firm connection ofthe magazine to the platen frame, or released for convenient removalthereof.

It will be understood that the weight of the magazine and its associatedparts, is

carried by one of the end members of the platen frame, the extension 12fitting therebe equal,

011, and having depending flanges 12 to secure it in position.

The extension 12 has an upstanding arm 12, to which is connected, at 12a friction wheel 24, which may have a corrugated larly equipped, saidwheel 25, being mounted on shaft 15, serving to drive said shaft and therolls 24 carried thereby. i

The feeding operation of the paper sheets to the platen will be wellunderstood from the foregoing description. The surface speeds of the'rolls '14 and the platen may to synchronize their action. Should thedegree of-frictional contact be tween wheel 24 and the platen requirevariation, thisv may be accomplished by tightening or'loosening the nut22", when a slight fall or rise-is obtainable, because an elastic aboutsaid rolls, said bands 14 being inbe rocked to the position shown inFig. 8,-

in which position said bail cams or applies pressure against the papersheets, moving their lower edges back over the base 13, and removingtheir forward surface from contact with the friction rolls'14, thedevice thus becomim inoperative.

It will be noted that no other fixed connections are employed inattaching the magazine apparatus to a typewriting machine, and the meansfor removably securing said apparatus to the carriage are of thesimplest character possible. Also, it should be noted that the magazineframe work, including the mounts and supports for the operative parts,may be composed of sheet metal, and, as illustrated in the example inthe drawings, may be stampedor formed out of a single sheet, therebymaking for economy in construction, besides giving the qualities ofstrength and lightness.

Variations may be resorted to within the scope of the'invention, andportions of the improvements may be used without others.
